3 Claims. 1

r .This invention relates to railroad cranes and more particularly it is an object of this invention to provide a crane particularly designed for attachment to the coupler of a railroad car. Many lifting jobs in railroad yards are at points disposed closely adjacent tracks upon which railroad cars are positioned. In lifting heavy objects by means of a crane it is necessary that the crane itself be anchored to a heavy solid base which is preferably movable. It is my concept that the common railroad car can be used as just such a base and is readily available for these purposes.

It is therefore an object of this invention to provide a crane adapted to be removably secured to the coupler of a railroad car.

Another object of the invention is to provide a crane as described having its block and tackle portion secured by means of a wheel along a trac'kway section of the crane whereby the block and tackle assembly can be moved back and forth.

Yet a further object of the invention resides in the I provision of a crane construction as described such that the inner end thereof is pivotally securable so that objects being lifted can be swung in an arc permitting their movement from one position to another with ease.

Still another object of the invention is to provide turnbuckle means for adapting the crane to various amounts of strain.

Yet another object of the invention is to provide a device for the purpose described which is sturdy and durable in construction, reliable and efficient in operation, and relatively simple and inexpensive utilize.

Other and still further objects and advantages of the invention will become apparent from the following detailed description of a preferred embodiment thereof.

In the drawings:

Figure 1 is a side elevation of the crane of this invention shown as secured to a portion of the coupler of a railroad car, the coupler being partially shown in section, the railroad car being partially shown in dotted lines, and the position of railroad tracks also being indicated in dotted lines.

Figure 2 is a top plan View of the crane of Figure 1 without the block and tackle, linkages, and traveler pulley wheel of the invention disposed in place thereon.

Figure 3 is a right end elevation of the crane shown with the block and tackle assembly reto manufacture, assemble and 2 moved and with. a left-hand portion of the cou pler broken away as shown in Figure l.

The crane of this invention is for attachment to the coupler H) of a railroad car, which latter is partially indicated in dotted lines at I2 disposed on railroad tracks partially shown in dotted lines at M.

The coupler It is shown in cross-section and is provided with two outstanding vertically spaced apart ears [8 which latter are provided with aligned holes 20 therethrough. r

The crane of this invention includes an elongated member generally indicated at 3?! having two end portions 32 and 33 disposed vertically offset from each other and preferably in parallelism with each other.

The outer portion 33 is disposed normally above the inner end portion 32 and the two portions are interconnected by an inclinedly disposed interconnecting portion 36. A bracing web 38 is provided disposed across and beneath the portions 33 and 36 at their point of joining.

The elongated member can be formed of hollow pipe, if desired, and the extreme inner end thereof is preferably flattened and is provided with an aperture 40 vertically disposed therethrough as indicated in dotted lines in Figure 1. The purpose of the aperture 46 is for receiving a bolt 42 which latter is disposed upright through the apertures 29.

The crane further includes an attachment member 58 disposed above and alon side 0f the inner end portion 32 of the member iii The inner end of the member 51] is flattened and is disposed in use above the upper ear H3. The said flat inner end of the member 50 is provided with an aperture 5:: shown in dotted lines in Figure 1. As thus described, the inner end of the members 39 and 50 are disposed above and resting upon the ears 18.

The outer end of the member 50 is provided with threads 58 for the reception thereon of a turnbuckle interconnecting member 60 and the outer end of the latter is threadedly secured to the thread 62 on the inner end of a brace member 64.

The brace member 64 extends alongside of and is disposed above the elongated member 30. The outer end of the member 64 is disposed in parallelism with and is welded or otherwise suitably secured to the upper side of the outer end 33 of the member 30. The brace member fi l is preferably formed of a round rod of lesser diameter than that of the member 30.

The brace rod 64 is preferably of a diameter .means of a pin 82.

complemental to the groove 66 of a pulley wheel 10 which latter is rotatably disposed on the outer end of the rod 64 and is held in such position by a yoke 80 to which it is rotatably secured by The pin 82 may be provided with nuts 84 if desired as is shown only in Figure 3.

The yoke 80 is preferably provided with outwardly bulged sides for extending around the member 30.

As best seen in Figure 1, a linkage iii! is provided for securing the yoke 89 to a substantially triangular-shaped swivel portion 94. The latter has a normally horizontally disposed lower side to which a swivel bolt 85 is secured.

The swivel bolt 96 is designed for securing the triangular member 94 to a .U-shaped member I and the latter extends around two opposite sides of the upper pulley l i ii of a block and tackle assembly.

The upper pulley HE is secured to the U- shaped member Hit by means of a pin H2 and a line I [-6 is disposed around the pulleys l iii and I25 of the block and tackle assembly.

The lower pulley N10 is secured by means of a pin I24 to a U-shaped member 536 of the assembly. The latter is secured to a hook I46 of the crane.

A stop member IN! is mounted on the forward ends of the members 33 and d and projects upwardly for preventing the pulley wheel if! from passing over the outer end of the member 64.

The web 38 prevents the pulley wheel it from traveling excessively inwardly along the member 30.

As thus described, this invention has provided a railway crane which can be readily secured to and removed from the coupler of a railroad car; which is adapted to pivot in a horizontal plane; and a crane the hook portion of which is adapted to be moved upwardly and downwardly by means of a block and tackle assembly.

From the foregoing description it is thought to be obvious that a crane hoist for railroad trucks constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that our invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason we do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts herein shown in carrying out our invention in practice except as claimed.

We claim:

1. In a railway hoist, the combination which comprises a car coupler having a pair of vertically spaced ears, a substantially vertically disposed pin carried by said ears, an outwardly and upwardly extended tubular bar having a horizontally disposed upper end pivotally mounted on said pin and positioned between the ears, a reinforcing brace connecting the horizontally disposed section of the tubular bar to the pin carried by the ears, and means adjusting the length of said reinforcing brace.

2. In a railway hoist, the combination which comprises a car coupler having a pair of vertically spaced ears, a substantially vertically disposed pin carried by said ears, an outwardly and upwardly extended tubular bar having a horizontally disposed upper end pivotally mounted on said pin and positioned between the ears, a reinforcing member connecting the horizontally disposed section of the tubular bar to the pin carried by the ears, means adjusting the length of said reinforcing member, and a pulley block rotatably mounted on the horizontally disposed section of the bar, said bar having a stop on the outer end limiting the travel of the pulley block.

3. In a railway hoist,'the combination which comprises a car coupler having a pair of vertically spaced ears, a substantially vertically disposed pin carried by said ears, an outwardly and upwardly extended tubular bar having a horizontally disposed upper end pivotally mounted on said pin and positioned between the ears, a stud also mounted on said pin and positioned above the upper ear, a reinforcingrod positioned above the said tubular bar having a horizontally disposed section mounted on the horizontally disposed section of the bar and having a downwardly extended end, a turnbuckle threaded on the downwardly extended end'of said reinforcing bar and also on the said stud, and a pulley block carried by the horizontally disposed sections of the tubular bar and reinforcing bar, the extended ends of the said tubular and reinforcing bars having a stop thereon for limiting outward travel of the pulley block.
